PROBLEM TO BE SOLVED: To provide a film for molding simultaneous transfer with enough molding properties and thickness uniformity in a width direction.SOLUTION: A molding simultaneous polyester film for transfer is the film laminating the layers comprising polyester of which carboxylic acid unit constituent includes 90-80 mol% of the terephthalic acid unit and 10-20 mol% of the isophthalic acid unit and glycol unit constituent includes 98-100 mol% of the ethylene glycol unit on both sides of the layers comprising polyester of which carboxylic acid unit constituent includes 94-88 mol% of the terephthalic acid unit and 6-12 mol% of the isophthalic acid unit and the glycol unit constituent includes 90-80 mol% of the ethylene glycol unit and 10-20 mol% of 1,4-cyclohexanedimethanol unit, wherein the thickness deflection per 1,000 mm in the film width direction is 4.0 μm or less, the film surface orientation coefficient &Dgr;P is 0.136-0.141, and the shrinkage in 150°C/5 min both in the length and breadth of the film are 0.0-8.0%. |
